Abstract
The present invention relates to a two-stroke self-boosting engine with paired cylinders. The present invention adopts the technology of paired cylinders, a single cylinder with four strokes is divided into a gas compression cylinder for completing a gas suction stroke and a gas compression stroke, and a work doing cylinder for completing a work doing stroke and an exhaust stroke. The gas compression cylinder and the work doing cylinder are matched in pairs to jointly complete one work cycle. The present invention adopts the technology of the paired cylinders to divide the functions of the cylinder, the volume of the gas compression cylinder is larger than that of the work doing cylinder, and the engine has a self-boosting function by the volume ratio of the gas compression cylinder to the work doing cylinder. Thus, the present invention has the advantages of high engine power, low oil consumption, sufficient combustion, small waste gas discharge amount and low noise.
Description
Technical field the invention belongs to the engine core technical field, specifically to the improvement of four stroke engine work done pattern.
The existing reciprocating engine of background technique is born over 100 years certainly, though done many improvement technically, but its four-stroke work done pattern is used till today, never change, no matter its cylinder number what, the cylinder diameter size, it is air-breathing, compression, igniting work done, exhaust all are to be finished successively by single cylinder, 180 ° of each strokes, and a work cycle is 720 °, that is to say that every two week of the rotation ability work done of bent axle once.An important channel of existing raising engine power performance and economic performance is to increase suction pressure or be referred to as air inflow, its technical measures are to utilize peripheral unit---the exhaust gas turbocharge device, increased the manufacture cost of motor, and effect and not really desirable.Therefore we can say, because the constraint of motor self work done pattern, limited the further raising of the further developing of its technology, efficient.
" gas-filled double stroke internal-combustion engine " (CN106491A) includes air-breathing and compressed air cylinder, work done and exhaust casing, inflation piston and connecting rod, work-doing cylinder and connecting rod.It couples together air cylinder and work-doing cylinder, and the pressurized gas in the compression cylinder is flowed to connecting tube of work-doing cylinder, air inlet-outlet pipe and blow off valve etc.The purpose that it joins a pressure cylinder with each work-doing cylinder is to improve scavenging efficiency, and the characteristic from supercharging is not arranged.
Summary of the invention the objective of the invention is existing motor four-stroke work done pattern is improved, and with under the prerequisite that does not increase motor gross weight and manufacture cost, can increase substantially the power of motor, reduces oil consumption, exhaust gas discharging and noise greatly.
The implementation of the object of the invention is, pairing cylinder two stroke supercharged engine, and the single cylinder that will have four strokes is divided into the air cylinder 1 of finishing air-breathing and compression stroke and finishes work done and the work-doing cylinder of exhaust stroke 11.Air cylinder, work-doing cylinder are a matched pair, and air cylinder cylinder appearance＞work-doing cylinder cylinder holds.Displacer 3, connecting rod 4 are connected with air cylinder crank throw 5, work doing pistons 7, connecting rod 8 are connected with work-doing cylinder crank throw 10, air cylinder crank throw 5, work-doing cylinder crank throw 10 are a single piece with bent axle 12, air cylinder, work-doing cylinder have suction tude 2, outlet pipe 9 respectively, between connecting tube 6 is arranged, each mouth of pipe has valve.10 of air cylinder crank throw 5 and work-doing cylinder crank throws have 15 °-45 ° minimum angle.10 minimum angles that have 15 °-45 °.
The present invention is divided into the single cylinder with four strokes the air cylinder 1 of finishing air-breathing and compression stroke and finishes work done and the work-doing cylinder of exhaust stroke 11 (see figure 1)s.The function of air cylinder is to suck fresh air and carry out precompression, again the gas after the compression is pressed into work-doing cylinder by connecting tube 6.The function of work-doing cylinder is to the pressurized gas igniting work done from air cylinder, and the waste gas after the work done is discharged outside the cylinder.What, size of the cylinder of motor no matter, air cylinder, work-doing cylinder are supporting in twos in pairs, finish work cycle of four-stroke jointly.
Working principle of the present invention is: when the displacer in the air cylinder 13 was descending from top dead center, the valve of suction tude 2 was opened, and sucked air, the piston 7 descending works done in the work-doing cylinder 11 in the air cylinder.When displacer arrival lower dead center began up calming the anger, work doing pistons was because advance angle has been crossed and has been advanced into exhaust stroke on the lower dead center, and gas of combustion is discharged from outlet pipe 9.
The stroke of calming the anger of displacer is divided into two stages from microcosmic, compression stage and calming the anger the stage.At compression stage, the gas that sucks in the air cylinder is compressed by the pressure of up displacer, and gas volume constantly reduces, and promptly enters the stage of calming the anger when reducing to after a certain amount of.In the stage of calming the anger, displacer continues up, and compressed gas pressure increases, big to connecting tube 6 liang of mouths of pipe valve wash open, pressurized gas is from enter work-doing cylinder connecting tube, and the work doing pistons in the work-doing cylinder has been finished exhaust stroke, begins to leave under the top dead center to be advanced into power stroke.The cylinder at two-cylinder piston top held variation tendency and was this moment, and the air cylinder cylinder holds constantly and reduces, and the work-doing cylinder cylinder holds constantly and increases, and the air cylinder cylinder holds and levels off to zero the time, and pressurized gas promptly all enters in the work-doing cylinder.This stage also has an outstanding feature to be, pressurized gas cognition is compressed for the second time because of air cylinder cylinder appearance＞work-doing cylinder cylinder holds, and the cylinder that the compression ratio of secondary compression equals two cylinders holds ratio.The present invention improves the purpose of power owing to the existence of secondary compression reaches from supercharging.As set the air cylinder cylinder and hold 3 times that hold for the work-doing cylinder cylinder, then the power of motor will improve 3 times.Theoretically, the cylinder of air cylinder and work-doing cylinder holds ratio can be infinitely great, and according to the real needs of motor, we can select corresponding cylinder and hold ratio in practice.
The present invention becomes two cylinders, two strokes with motor by single-cylinder four-stroke, and two cylinders are respectively finished its function, finishes a work cycle jointly.Air cylinder cylinder appearance＞work-doing cylinder cylinder holds, and motor has from function of increasing pressure, can increase substantially power.The present invention adopts high air-fuel ratio, and the burning of motor friction speed all is controlled in the chemically correct fuel, can effectively reduce oil consumption.Because higher air fuel ratio is arranged, can make fuel combustion abundant, thereby reduce the discharge of harmful gases amount, reduce environmental pollution.Owing to adopt the principle of limit air-breathing limit burning, overcome the noise that existing engine flare formula burning produces, noise is greatly reduced.The present invention is applicable to all reciprocating engine as a kind of new work done pattern, and no matter its fuel type, cylinder number what, cylinder diameter size all can adopt.

Embodiment is for making the good teamwork of pairing cylinder, the air cylinder crank throw 5 and 10 of the work-doing cylinder crank throws that are connected on the bent axle 12 have one 15 °-45 ° angles (seeing Fig. 2,3), this angle had both shown as the advance angle of work-doing cylinder to air cylinder in work cycle, also define the size of air cylinder gas compression ratio simultaneously.Pass between minimum angle and air cylinder gas compression ratio is an inverse relation, and promptly minimum angle is big more, and compression ratio is more little, and minimum angle is more little, and compression ratio is big more.
